[PATCH 1/3] ARM: omap2+: set IRQCHIP_SKIP_SET_WAKE for INTC interrupts.

[NeilBrown]

All interrupts can wake-from-sleep (I think) so it should be
permissible to call enable_irq_wake().  Setting this flag allows that.

It is needed because without this, an interrupt which is delivered
during late suspend will get ignored but will not cause suspend to
abort.
If enable_irq_wake() is called and succeeds, check_wakuep_irqs()
will abort the suspend if the interrupt has fired.
